[issue976880] mmap needs a rfind method

[John Lenton]

John Lenton added the comment:

Attached patch adds two things: an 'end' argument to find, and an
'rfind' method. This includes minimal tests for rfind, but as I actually
refactored find and rfind into a single method, tests covering find also
cover most of rfind :).  I added 'end' first because the refactoring
seemed more natural (symmetric?) after that. Also included are updated
docs, and NEWS.
